摘要

The Three Gorges Reservoir (TGR) has a peculiar hydrological regime in China, with water level fluctuations of 30 m annually. In order to investigate the effects of hydrodynamic conditions on the diatom communities, limnological investigations were conducted monthly in front of the Three Gorges Dam (TGD) in 2013. We identified 18 diatom genera from two classes. The spatio-temporal patterns of diatoms showed an apparent heterogeneity. During the flood season (May October), high flows, high veloci
